Detailed Description

QGraphicsRectItem with an application-defined type integer and center-point helpers.

RectangleGraphicsItem stores a type integer (returned by type()) that allows qgraphicsitem_cast<> and scene item-type filtering to work with custom types. It also provides centerPoint() and sceneCenterPoint() convenience accessors.
